Abstract:Objective To investigate the clinical application of absorbable barbs line in gallbladder-protected lithotomy by laparoscopy combined with choledochoscopy. Methods A retrospective analysis was used to analyze the clinical data of 209 patients treated with gallbladder-protected lithotomy by laparoscopy combined with choledochoscopy in our department from June 2015 to January 2018. Among them, the patients whose gallbladders were sutured with absorbable barbs line were enrolled in barbs line group, and patients whose gallbladders were sutured with common absorbable line were enrolled in control group. Results Among 209 patients, the barbs line group contained 128 cases, the control group contained 81 cases. There was no significant difference in general baseline data between the two groups (P > 0.05). There was no significant difference in intraoperative bleeding volume and average hospitalization time between the two groups (P > 0.05). In barbs line group, the suturing gallbladder time was (5.52 ± 1.32) min, and the operation time was (64.87 ± 16.36) min; in control group, the suture gallbladder time was (6.19 ± 1.64) min, and the operation time was (72.80 ± 25.09) min; and both time in the barbs line group was significantly less than the control group (P < 0.05). In barbs line group, there was no bile leakage occurred, but the incidence of bile leakage was 6.17% (5/81) in control group. There was a significant difference between the two groups (P < 0.05). Three cases of bile leakage were relieved after conservative treatment, and two cases were relieved after endoscopic nasobiliary drainage. The follow-up period was 3-6 months. Stone recurrence happened in 13 cases. Then 6 cases underwent laparoscopic cholecystectomy and other 7 patients of sludge stones underwent endoscopic sphincterotomy/endoscopic papillary balloon dilatation plus endoscopic nasobiliary drainage, then the sludge stones disappeared. There were no death related to operation. Conclusion It is safe and feasible to use absorbable barbs line to suture gallbladder in gallbladder-protected lithotomy by laparoscopy combined with choledochoscopy. It can significantly reduce the difficulty of laparoscopic suture gallbladder, shorten the suturing gallbladder time and operation time, and reduce the incidence of bile leakage after operation. It had important clinical significance and advantage.
